[o all tvhrom'z may concern:

Be it known that'I, VAL'R G. Wiinnok, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Gages, of which the tfollowing is a specification.

This invention relates to improvements in means for protecting and supporting water gage tubes of steam boilers and may be considered as an adjunctto my Patent No. 1213986 andto my pending application bearing Serial No. 84,920. Specifically my present invention contemplates the provision of means for almost instantly inserting or removing` the gage glass, when necessary, without the use of tools of any kind and without disturbing any of the parts of the protector. A further object is to provide means for tightening the gage glass in operative position without exerting a torsional strain upon the glass. means for centering the gage glass in the elements supporting the same thereby avoiding binding of the glass against said elements; and means are also provided for directing the steam directly into the center of the gage glass thereby eliminating corrosion of the upper end of the glass due ordinarily to the action of the steam. A still further object is to provide a device of this type in which the valves are so constructed that they may be instantly removed to be reground without disturbing anv of the other parts of the device.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings which :form a part of this specification and in which- Figure 1 is a side elevation, partly in section to alord a better illustration, of one embodiment of my present invention illustrating its application.

F ig. 2 is a front view partly in section and is taken on line 2-2 of Fig. 1.

Like reference characters denote corresponding parts in both views.

Thel reference numeral 1 denotes a steam boiler or water column provided with the hand valves 2 and 3 fitted to valve casings 4 and 5 which are connected. respectively, by nuts 6 and 7 with the nipples 8 and 9 that A further object is to provide lead to the steam and water spaces ot' the boiler or water column 1. T he valve casings 4, 5 are formed with vertical alined bores 10, 11, the casing 5 being formed, further, with a threaded. blow-out connection 11ZL and with an annular shoulder 12 through which the bore 11, reduced in diameter, extends. rIhe casing 4 has the upper end of its bore 10 reduced in diameter to form a steam passage 1()a thus forming an annular shoulder 10b which directs the steam into the center of the gage tube 19 and not against the end of that tube as in the ordinary gage. Corrosion of the end of the tube is thereby avoided. The casing 4, further is provided with the packing box 13 formed with lateral ears 14 through which the adjusting screws 15 extend that connect said ears with the end plate 16 of said casing, said adjusting screws being operable by means of their thumbnuts 17. A packing ring 18 within the packing box 13 is normally retained against the lower termination of the casing 4 and encircles the gage glass 19 which extends into the packing box and into said casing. The said gage glass, at its lower end extends through another packing box 20 secured to the casing 5 into the casing and rests upon the annular shoulder 12 of that casing and is encircled by a packing ring 21 similar to the packing ring 18 and which rests upon the upper end of the casing. Adjusting screws 22 connect ears 23 of the packing box 20 to a base plate 24 and tosaid casing 5, said base plate and casing being also secured together by said adjusting screws.

The plates 16, 24 are also connected by the terminally threaded rods 25 which are individually removable and which also carry straight or segmental back plates 26 that are grooved to carry the back or reflector as shown. If desired the rods 25 may be removed and the type of swinging gage glass protector shown in my pending application above specified, or any type of swinging protector that can be carried upon pintles or rods similar to the rods 25, may be substituted.

To insert a gage glass 19 it is but necessary to insert one end of the glass through the opening in the packing box 1S and push it well into that box, the lower packing box being removed at the time. The lower packing box 20 is now placed in engagement with the gage glass and moved upwardly over the same to permit it to clear the valve casing 5. The lower end of the gage is then inserted in the casing 5, the packing box put in place upon said casing and the glass tightened in position by means ofthe thumb nuts 17. As

these nuts are tightened against the packing boxes they move them tightly against their respective casings and also force the packing rings to firmly grip the gage glass. The glass is easily and readily removed by simply reversing the operation described. The packing rings, when tightened against the gage glass, center the same and serve to hold it rigidly in position Without exerting a torsional strain upon it.

What is claimed is 1. In a Water gage comprising oppositely disposed valve casings, said valve casings being formed with inner annular shoulders; packing boxes adapted for removable close fitting engagement with said valve casings,

a gage tubeadapted for removable insertion in said valve casings and packing boxes, one end of said gage tube being adapted to rest iupon the said annular shoulder of one valve casing, packing rings arranged in said packing boxes for engagement With the ends of said valve casings and encircling said gage tube, adjusting screws connecting said packing boxes and valve casings, and thumb nuts arranged upon said adjusting screws.

2. In a Water gage comprising oppositely disposed valve casings, said valve casings being formed With inner annular shoulders;

packing boxes adapted for removable close 1 fitting engagement with said valve casings,a gage tube adapted-for removable insertion in said valve casings and packing boxes, one end of said gage tube being adapted to rest upon the said annular shoulder of one valve casing, centering and tightening means for said gage tube Within said packing boxes, and manually operable means connecting said packing boxes and valve casings Whereby the former may be moved relatively to the latter to actuate said centering and WALTER G.
